Estopped from defending the Donation, since it never existed and, if it had existed, it would now have expired from lapse of time, our adversaries take refuge in another kind of defense; figuratively speaking, the city being given up for lost, they betake themselves to their citadel,—which forthwith they are constrained by lack of provisions to surrender. “The Roman church,” they say, “is entitled by prescription to what it possesses.” Why then does it lay claim to that, the greater part, to which it has no title by prescription, and to which others are entitled by prescription; unless others cannot act toward it as it can act toward them? The Roman church has title by prescription! Why then does it so often take care to have the Emperors confirm its right? Why does it vaunt the Donation, and its confirmation by the Caesars? If this alone is sufficient, you seriously weaken it by not at the same time keeping silent about the other title [by prescription]. Why don’t you keep silent about that other? Obviously because this is not sufficient. The Roman church has prescribed! And how can it have entered a prescription where no title is established but only possession through bad faith? Or if you deny that the possession was a case of bad faith, at least you cannot deny that the faith [in the Donation] was stupid. Or, in a matter of such importance and notoriety, ought ignorance of fact and of law to be excused? Of fact, because Constantine did not make a grant of Rome and the provinces; a fact of which a man of the common people might well be ignorant, but not the supreme pontiff. Of law, because they could not be granted; which any Christian ought to know. And so, will stupid credulity give you a right to that which, had you been more conscientious, would never have been yours? Well! Now, at least, after I have shown that you held possession through ignorance and stupidity, do you not lose that right, if it was such? and what ignorance unhappily brought you, does not knowledge happily take away again? and does not the property revert from the illegal to the legal master, perchance even with interest? But if you continue to keep possession in the future, your ignorance is henceforth changed into malice aforethought and into deceit, and you become a fraudulent holder.
